37.5.3 Warning Options

These variables are used by users to control what happens
when a Lisp program reports a warning.

— User Option: warning-minimum-level

This user option specifies the minimum severity level that should be
shown immediately to the user. The default is :warning, which
means to immediately display all warnings except :debug
warnings.

— User Option: warning-minimum-log-level

This user option specifies the minimum severity level that should be
logged in the warnings buffer. The default is :warning, which
means to log all warnings except :debug warnings.

— User Option: warning-suppress-types

This list specifies which warning types should not be displayed
immediately for the user. Each element of the list should be a list
of symbols. If its elements match the first elements in a warning
type, then that warning is not displayed immediately.

— User Option: warning-suppress-log-types

This list specifies which warning types should not be logged in the
warnings buffer. Each element of the list should be a list of
symbols. If it matches the first few elements in a warning type, then
that warning is not logged.
